First Things First: Setup and Initial Focus
Before you even step on the first tee, take a couple of minutes to set up your Redtiger for your own eyes. This is a step most golfers skip, but it makes a significant difference in how quickly and clearly you can lock onto your targets. The most important part of this is adjusting the diopter, which is just the technical term for the adjustable eyepiece.
Here’s the simple process:
Charge It Up: Most Redtiger models come with a USB-C charging port. Give it a full charge before your first use so you don't have to worry about it dying mid-round. The battery life is generally excellent, lasting for several rounds, but it's always good practice to start fresh.
Power It On: Press the power button once. You’ll see the display light up, showing the aiming reticle (the crosshair) and other information.
Adjust the Eyepiece: Now for the important part. Bring the rangefinder up to your eye and look through it at something in the distance, but don’t try to get a distance reading yet. Just look at the display itself - the numbers and the crosshair. Rotate the adjustable eyepiece ring until the digital display is perfectly sharp and in focus for your vision. If the numbers look crisp, you've done it correctly. This ensures that every time you look through it, both the reticle and the yardage reading will be crystal clear.
Taking 30 seconds to do this means you won't be fumbling on the course, trying to get a clear view while your playing partners are waiting. You've dialed it in for your eyes, and now you're ready to go.

Mastering the Basics: Point, Shoot, and Get Your Number
At its heart, a rangefinder is straightforward. Its primary job is to tell you exactly how far away a target is. The core function of your Redtiger is incredibly easy and intuitive. You aim, press a button, and get a number. It's that simple.
Here’s the play-by-play:
Aim Your Target: Look through the focused eyepiece and place the crosshair directly on your target. For an approach shot, this will almost always be the flagstick.
Press the Power/Fire Button: Press the top button once. You’ll see the display activate and a laser will fire (it's invisible and harmless). In a fraction of a second, the distance will appear on the display.
That's it. You now have the exact line-of-sight distance to the pin.
A Quick Coaching Tip: Stability is your friend. If you have shaky hands, it can sometimes be tough to hold the crosshair steady on a skinny flagstick from 180 yards away. To steady yourself, try tucking your elbow into your side or bracing it against your chest. Alternatively, use both hands, similar to how you’d hold a pair of binoculars. This simple act of stabilization makes it much easier to hit your target and get a reliable number quickly.
Unlocking the Power: Understanding Your Redtiger's Modes
Getting a single yardage is useful, but the real advantage of a modern rangefinder like the Redtiger comes from its different modes. Learning what these do and when to use them is what separates the average user from a golfer who uses technology as a real weapon. Most Redtiger models have two or three main modes you should know about, operated by the "M" or Mode button.
General Scan Mode
Sometimes you need more than just one number. You need a complete picture of the area you’re hitting into. This is where Scan Mode comes in. By pressing and holding the power button, the rangefinder will continuously measure and update the distance as you pan it across different targets.
How to Use It: Aim at the first point of interest, then press and hold the power button down. Without letting go, sweep horizontally across your landing area. Watch the numbers change in real-time.
Practical Application: Imagine a green protected by a large bunker in the front. Instead of just getting the number to the pin, you can use Scan Mode to find out everything you need to know:
Scan the front lip of the bunker: 135 yards to carry.
Scan the flagstick: 150 yards.
Scan the back edge of the green: 160 yards to the back.
Within about three seconds, you’ve just mapped the hole. You know a 140-yard shot is safe, a perfect 150-yard shot is ideal, and anything over 160 yards is trouble. This is course management at its finest.
Golf Mode with Slope Compensation (and the Tournament Switch)
This is arguably the most powerful feature for improving your club selection. A 150-yard shot that’s significantly uphill plays much longer than 150 yards. A downhill shot plays shorter. The Slope feature does the math for you.
How it Works: When you're in Slope mode, the Redtiger measures both the direct distance and the angle of elevation change. It then calculates and displays two numbers: the actual line-of-sight distance and the "plays like" or adjusted distance. The "plays like" number is the one that matters - it's the true yardage you should select a club for.
On-Screen Display: You'll typically see the actual yardage, the angle of the slope (e.g., +4° for uphill), and the adjusted yardage, which is often displayed larger or more prominently. That larger number is your go-to. A 140-yard shot with a +5° slope might give you a 'plays like' distance of 152 yards. That’s probably the difference between a 9-iron and an 8-iron.
The Tournament Switch: Slope calculation provides incredible data for your practice rounds, but it's not allowed in most official competitions. Redtiger rangefinders feature a visible, physical switch on the side of the device. When you slide this toggle, the slope functionality is turned off, making the device fully compliant with USGA and R&,A rules. Simply slide it back on for your next friendly round.
Flag-Locking with Vibration
Ever been unsure if you lasered the pin or the trees directly behind it? We’ve all been there. This feature solves that problem. The Flag-Locking (or Pin-Seeking) technology intelligently prioritizes the closest target in the crosshairs, and once it confidently identifies the flag, the device gives a short vibration or pulse.
How to Use It: Just aim in the general direction of the pin and hold the power button. Even if your hand is a bit shaky and the crosshair moves between the flag and the background, the technology will lock onto the flag.
The Benefit: That little buzz is your confirmation. It’s the device giving you the a-ok, saying "I found the pin." It removes all doubt from the number on your screen. You have the exact yardage to the flag and can swing with 100% commitment.
Plan every shot like a pro

Once you’re comfortable with the settings, you can start using your Redtiger like a tour caddie would, by thinking beyond just the distance to the pin. A rangefinder is for gathering intelligence for every shot, not just your approaches.
Shoot Hazards and Landing Zones: On a long par-4 or a dogleg, the number to the pin is irrelevant from the tee. Use your rangefinder to get the critical distances you actually need. How far is it to carry that fairway bunker? What's the distance to that tree you want to use as a lay-up target? Shooting these reference points allows you to build a smart strategy for playing the hole.
Measure Your Drives: Curious how far you actually hit that last tee shot? Once you get to your ball in the fairway, turn around and shoot the tee box. It’s a great way to learn your real-world carry distances.
Combine Tech with Feel: Your rangefinder gives you an exact, unemotional number. It’s perfect. But it can’t feel the 15 mph wind in your face or see that you have a fluffy lie. Your job is to take the perfect number from the device and adjust it based on the conditions. The Redtiger gives you the data, you provide the golfer’s touch.
Keep Your Lenses Clean: This sounds obvious, but a smudge on the lens can interfere with the laser and affect accuracy. Just as you clean your clubs, give the lenses a quick wipe with a microfiber cloth before a round to ensure your device is performing at its best.
